SPECIFICATION formingpaa or Letterslratent No. 704,732, dated July 15, 1902- Application led January 16,1902. Serial No. 90.031. (No modela introducing compressed air and the oil and for comminuting. the oil and interminglin g or mixing it with the air and heating the mixture and jetsv through which it is discharged, with means for delivering it to the point Where combustion is to take place.

My invention also comprises details of construction, Which will be more fully explained by reference to the accompanying drawings, in which- Figure l is a vertical longitudinal section,

partially in elevation, through the apparatus. y

The object of my invent-ion isntoprovide a. more perfect means for intermingling or mix-` ing air and oil products and preparing them for burning, and preferably partially-retined oil.

As here shown, A is an exterior caseof any suitable or desired form and dimensions and adapted to contain the cylindrical tubes 2 andA 3, one of Which is located above the other,

and bothV are suitably supported Within the casing. The upper -tube 2 has a conical d ischarge-nozzle at el, through which. the mixed.y air and oil are discharged, and 'the casing Ay has its front also reduced into a conical form,

as at 5, with the opening larger in diameter and approximately concentric with the nozzie 4.

The air and oil are mixed and introduced into the rear of the cylinders 2 and 3 in the following manner: v

6 is a sleeve having bolt-hangen at each end, and at'one end is fitted a cap 7, having an inwardly-projecting Atubular cylindrical portion 8, into the rear end of which an air inlet pipe 9 is iitted, the discharge from this pipe being controlled by a suitable valve, as at l0. The annular chamber 8 may be of smaller diameter than the interior of the sleeve 6, and its front end is made conver gent or conical on the outside, and this conical front has tapering channels made in it,as shown at 11, all converging toward the end. The interior of the tube is also converged to the discharge-passage l2; but in some cases the part 8 may iill the interior of 6, and the channels 1lY extend to the rear end ofthe cylindrical part. A second jianged sleeve 13 is bolted to the end of the sleeve 6, as shown,

and is chambered to receive an annular circular piece 14, Which slips into the part 6 and is held Vin place when the part 13y has been boltedv to 6. The endet thislpiece 14 which is contiguous to the channels 1l of the part 8 is made concave, with the same taper as the' front end of 8, so that it fits against the conical portion, and thus leaves onlyv the open channels 1l, the ends of Which, converging as shown, discharge around the opening 12. Oil is admitted into the annular space or channels V8 around S through a pipe 15,having acontrolling-valve, as at 1G, and the oil thus admitted,

'under Suchrlessrre as may bedesirahle. fills the channels or space between thef outsidefof ycent to the conical front of 8 a thin iiat disk 19. Between the spiders 17 istted a propeller-wheel 20 of any suitable form, soV that When a jet of air is discharged through the passage 12 it Will pass through the openings IOO of the spiders 17 and impinging against the wheel 2O will cause it" to revolve, thus revolving the disk 19, which is fixed upon the end of the same shaft or`spindle. The operation of this portion will then be as follows: The oil and the air being concentrated and discharged against the disk 19 while the latter is rapidly revolving, the oil will be thrown outward into the chamber within which the disk revolves and finelysubdivided and at the same time mixed with the'air, the mixture passing through the spiders and being delivered through the passage 2l into the rear of the chamber 2 or 3 to which it appertains. I have here described but one of these devices, because each of the chambers 2 and 3 has a like device for supplying them. This portion of the apparatus is here shown as located behind the main chamber A, and the passage 2l is formed Within a sleeve which is bolted to the outer end of the sleeve 13 and extends through the rear of the case A to its attachment With the part 2 or 3 to which it belongs.

Upon each side of the vaporizer 2 are located perforated pipes 22, and beneath this chamber is located another similar pipe 23. Upon each side and beneath the chamber 3 are located similar perforated pipes 24:, as plainly shown in Fig. 2. Within the casing and beneath these vaporizers 2 and 3 is a space 25, adapted to receive any suitable fuel for the preliminary heating up of the apparatus.

In such an apparatus as I have described it is desirable to use an oil which has been partially purified and relieved of the heavy asphaltic base and other impurities, which would soon clog and obstruct such an apparatus as here described, and with the higher grade of oil the inlet may be reduced by making the cylinder 8 to fit closely within 6 and continuing the channels 11 to the inlet end, where they may connect with an annular groove, into which the oil is admitted from the valve-controlled pipe 15. This enables the user to control the supply and regulate it at will.

It will be understood that the generatingchamberA may be independent from the combustion-chamber, as when used for blast or other furnaces, or it may be a part of the furnace itself; but in my construction it is Well to protect the mixing-chambers,heretofore described, from the heat of the generator, and this is effected by means of a water-jacket 26, which surrounds the section 13 or 2l contiguous to this part of the apparatus, and a continuous supply and discharge will keep this part cool and prevent the mixer from being unduly heated.

If the apparatus is to be used in conjunction with a blast or equivalent furnace, it is desirable to supply air to enter the furnace with the gas generated within the apparatus, and this is effected by means of convergent openings 27, into which the nozzles 4 or 5 are insel-ted so as to have annular channels around them, and the blast from these nozzles will produce an inward draft of air through the openings 27 suicient for the perfect combustion of the gas.

When the apparatus is to be used in connection with a steam-boiler or similar furnace, the separate casing A may be dispensed with and the generator 2 located within the furnace-walls, and the connection from the mixer through the passage 21 would then be through the front wall of the furnace. With this construction the form of the heater 3 Will be changed, as shown at 3, in which the tube is preferably made in sections divided longitudinally and vertically and having slits 28 made along the top and intermediate rectangular portions 29, through which bolts may pass to secure the sections together. In this construction the mixed oil and air enters the pipe or pipes 3LL and passing out through the slits will heat the upper generator 2, and the discharge from one or more of these generators will fill the furnace with ame. In this construction air may be admitted by the usual or any suitably-controlled openings.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is-

1. The combination in an oil-burner of independent generating-chambers one located above the other and one yof said chambers having a discharge-nozzle, a casing inclosing both chambers, means for admittingy air and oil into each of said chambers and means for heating the chambers.
